Overview
Brief Summary
The purpose of this study is to explore the pharmacodynamics (PD), pharmacokinetics (PK), safety, and tolerability of multiple doses of RDEA3170 administered in combination with febuxostat compared to RDEA3170 administered alone and febuxostat administered alone in Japanese adult male subjects with gout or asymptomatic hyperuricemia.
